Because an atheist typically doesn't have religion. Only a militant atheist hates religion and everyone who belongs in a religion. The more militant they are the more the seek to destroy religion. That is why I went to militant atheist.
I know non-Christians celebrate Christmas. But if this parade or whatever had a nativity scene portrayed in it, there are certain militant atheist who would try to use the courts to stop that.
Some of them seem to specifically drive around the country looking for the next sign of Christianity on public land. They frequently have had 10 commandment monuments taken down from courthouses in a 90% or above Christian city and county.
There was a WWI monument out in the middle of nowhere on a dirt road miles away from civilization, in the Mojave Desert in California, that some atheist found out about and got their panties in a bind to have it taken down. It was a crucifix.
Those people are not representing the area the come into to have stuff taken down. They don't live there. They have no real purpose in life other than to cause strife and unrest just so they can feel morally superior. It is malignant narcissism.
Before the United States decided on "In God We Trust" being the national motto, Benjamin Franklin was lobbying hard for "Mind Your Business" instead. I wish that in some way we would have listened to Benjamin Franklin. Because if it isn't bothering anyone who lives there then Mind your own business. And if you don't live that and it bothers you then don't visit there.
If you don't like a state that prohibits atheists from holding office then don't live there. The founding fathers were real big on voting with your feet if the ballot box didn't work. Just move. If it isn't bothering anyone in that state, except for you and a handful of others, then move.
If when the Boy Scouts didn't want to allows gays or girls in their organization, if you didn't like it then start your own scouting organization that does. If a state didn't believe in gay marriage then move to a state that does. If Texas passes a bill that will allow private citizens to sue abortion doctors and that bother you then move.
This is a free country and way too much damage from the left has happened in this country. Because the left don't believe in freedom, they only believe in compliance and conformity.
